Unifrax introduces new Li-ion anode technology

Unifrax has announced that its new proprietary technology, SiFAB (Silicon Fiber Anode Battery Technology), which is currently in advanced testing after years of R&D, has shown promising performance in multiple battery systems, enables higher energy density, and has demonstrated incremental Si loadings of greater than 40 percent.

“SiFAB is the latest development from our long-standing tradition of using fiber-based technologies to create step-change value for our customers,” commented VP Chad Cannan. “This is a unique proposition in the market—Unifrax is a large, global manufacturing company introducing game-changing advanced silicon anode materials that can be used in existing manufacturing processes.”

“This transformational material presents numerous opportunities throughout the Li-ion battery ecosystem, with applications spanning personal devices, energy storage, electric vehicles and the broader industrial market,” added CEO John Dandolph. “SiFAB represents another addition to our robust EV and battery solutions portfolio, which includes AGM separator materials, large format Li-ion glass separators, interstitial thermal runaway barriers and battery compartment fire protection systems.”

SiFAB is Unifrax’s first step into silicon fiber for Li-ion batteries. The company expects production to come online in early 2022, and plans to build thousands of tons of long-term manufacturing capacity.
